“…The presence of these chemicals adds complexity to the greywater composition and can affect its properties such as pH, foamability, and biodegradability 30 . In comparison to broader wastewater matrices, which include sewage and industrial effluents, laundry greywater is typically less contaminated with pathogens, mainly arising from washing fecal-contaminated clothes 39 . However, it may contain similar levels of certain pollutants, such as surfactants and heavy metals, depending on the source.…”

This study explores the optimization of iron electrocoagulation for treating laundry greywater, which accounts for up to 38% of domestic greywater. Characterized by high concentrations of surfactants, detergents, and suspended solids, laundry greywater presents complex challenges for treatment processes, posing significant environmental and health risks. Utilizing response surface methodology (RSM), this research developed a second-order polynomial regression model focused on key operational parameters such as the area-to-volume ratio (A/V), current density, electrolysis time, and settling time. Optimal treatment conditions were identified: an A/V ratio of 30 m2/m3, a current density of 10 mA/cm2, an electrolysis duration of 50 min, and a settlement period of 12 h. Under these conditions, exceptional treatment outcomes were achieved, with turbidity removal reaching 94.26% and COD removal at 99.64%. The model exhibited high effectiveness for turbidity removal, with an R2 value of 94.16%, and moderate effectiveness for COD removal, with an R2 value of 75.90%. The interaction between the A/V ratio and electrolysis time particularly underscored their critical role in electrocoagulation system design. Moreover, these results highlight the potential for optimizing electrocoagulation parameters to adapt to daily fluctuations in greywater production and meet specific household reuse needs, such as toilet flushing. This tailored approach aims to maximize contaminant separation and coagulant efficiency, balance energy use and operational costs, and contribute to sustainable water management.

“…Biofilters are having the potential application to treat greywater and reuse (Hatt et al 2007;Jung et al 2019). RTC [Real Time Control] strategies with validation techniques for biofilters for efficient water quality to harvest and reuse through long term experimentation may be applied and found that nutrient and sediment removal was high with RTC (Shen et al 2019).…”

Stormwater drainage in urban areas have become a challenge due to the rapid and random growth of urban areas, removal of vegetation, reduction in the effectiveness of drainage infrastructure, climate change. Sustainable Urban Drainage Systems (SUDS), Low Impact Development (LID), Best Management Practices (BMP), Water Sensitive Urban Design (WSUD) and Sponge City Programme (SCP) are various aspects for urban stormwater management in a few parts of the world. Urban hydrology plays a vital role in the urban stormwater management system. However, optimal results can only be possible when the combined effect of climate change, land use patterns, reuse, treatment, ecology, and societal aspects are considered. There is a need to provide sustainable and resilient urban drainage systems to manage stormwater more efficiently. The present review has thoroughly discussed various features related to urban stormwater management, highlighted key drivers, identified knowledge gaps in each of the measures and/or practices, recommended future research needs of urban stormwater management to become sustainable and resilient. Integrated modelling approach considering various key drivers including reuse and real time governance enables stormwater management sustainable and resilient in urban environments.

“…Jung, Fowdar, Henry, Deletic, and McCarthy (2019) studied the feasibility of pathogen removal from light graywater using eighty biofilter columns under controlled conditions over a 12‐month period. It was found the event size and the design of saturated zone were critical for microorganism removal.…”
